*Stresses above those listed above could cause permanent damage to the device. This is a stress rating
only and functional operation of the device at any other condition above those indicated in the operation
sections of this specification is not implied.
Note: When powering this device from laboratory or system power supplies, it is important that the
Absolute Maximum Ratings not be exceeded or device failure can result. Some power supplies exhibit
voltage spikes on their outputs when the AC power is switched on or off. In addition, voltage transients on
the AC power line may appear on the DC output. If this possibility exists, it is suggested that a clamp circuit
be used.
